Trigger an n8n workflow from Budibase

Setup

Within n8n create a Webhook trigger node. Optionally configure the Authentication, and select the desired HTTP Method.

Click on the webhook URL to copy it to clipboard. You can start with the Test URL to make sure things are working as expected before using the Production URL.

Connect additional nodes to your n8n webhook trigger as desired.

Budibase DB node

It is also possible to connect to the Budibase DB within your n8n workflow using the budibase-db-n8n-node.

Authorization

The authorization field is optional, and represents the Authorization HTTP header.

The automation action step will return with a 401 error if the Authorization field is not set:

In the case of Basic auth you need to provide the header in the following format:Basic BASE64_ENCODED(username:password), which would look result in something like this:

Keep credentials safe

Ideally you should not save credentials as plain text in your Budibase apps. Use Environment variables πŸ”’ to keep these credentials safe!
